Killing red ants bait formulationTechnical field
The present invention relates to desinsection bait formulation technical field, especially a kind of killing red ants bait formulation.
Background technology
Red fire ant, is subordinate to Hymenoptera: Formicidae insect, and health is brownish red, and build is larger than general ant, becomes long 3 millimeters ~ 6 millimeters of polypide.Red fire ant is one of biological invasion with destructive power most that World Conservation Union includes, and has huge lethality to the mankind and animals and plants.Red fire ant is derived from South America, the U.S. is imported into the thirties in 20th century, and spread to Australia and Taiwan from the U.S. by cabinet case and turf at the beginning of 21 century, then import Wuchuan City of Chinese Guangdong province by household refuse again into from Taiwan again, then spread to other cities inside the province and Hong Kong, Macao.
Red fire ant strong adaptability, feeding habits are mixed, and have stronger fertility and aggressiveness, and new incoming area can be broken out in a short time and cause disaster.The harm that red fire ant produces mainly contains: one is harm agricultural production security, and red fire ant takes food the seed of crop, fruit, young shoot and root system, destroys the normal growth of plant, causes crops Severe Reduction even to have no harvest; Two is that red fire ant stings and stings people and animals, after human body is bitten by red fire ant, and pain as often burning just like fire, there will be bubble thereafter, it is even dead that minority allergic human population also can produce anaphylactic shock; Three is destroy communal facility, and red fire ant is usually built ant nest in the equipment such as electrical equipment, causes wire short-circuiting or facility failure.Therefore, to the control of red fire ant be the key subjects of international concern always.
At present, the red fire ant of the chemical bait formulation control of main employing both at home and abroad, existing chemical bait formulation is prepared from primarily of insecticide, bait, preservative etc., wherein, bait many employings bone meal, spices, corn flour, soybean meal etc., but the cost of these baits is all higher, poor to the attracting ability of red fire ant, food ingestion is few, wastes a large amount of grain resources and contaminated environment.
Summary of the invention
The object of this invention is to provide a kind of killing red ants bait formulation, this bait formulation can solve the problem of existing fire ant bait agent attracting ability difference.
In order to solve the problem, the technical solution used in the present invention is:
A kind of killing red ants bait formulation, be prepared from by the raw material of following percentage by weight: ethiprole 0.05% ~ 0.2%, Nipagin complex esters 0.2% ~ 0.5%, cassava ground-slag 70% ~ 85%, molasses 10% ~ 20%, surplus is water.
In technique scheme, technical scheme can also be more specifically: the percentage by weight of described raw material is respectively: ethiprole 0.05%, Nipagin complex esters 0.5%, cassava ground-slag 70%, molasses 20%, water 9.45%.
Further, the percentage by weight of described raw material is respectively: ethiprole 0.2%, Nipagin complex esters 0.35%, cassava ground-slag 78%, molasses 15%, water 6.45%.
Further, the percentage by weight of described raw material is respectively: ethiprole 0.1%, Nipagin complex esters 0.2%, cassava ground-slag 85%, molasses 10%, water 4.7%.
The powder that the ground special product cassavas such as cassava ground-slag is Guangxi, Guangdong, Hainan dehydrate after starch isolation, main component is starch and cellulose, a small amount of protein.In cassava process, produce a large amount of cassava ground-slag, cassava ground-slag is cheap, is rich in red fire ant and ingests the nutrient components such as required starch, protein.Molasses are by products of sugar industry, are rich in red fire ant and ingest the nutrient components such as required sucrose, protein.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention is using cassava ground-slag with sugar is close is applied to killing red ants bait formulation as bait, cassava ground-slag and sugar is close is easy to get at Guangxi province raw material, cheap, not only achieves the recycling of refuse, and reduces the production cost of fire ant bait agent.
2, cassava ground-slag and sugar is close is rich in the nutriment such as carbohydrate and protein is red fire ant institute eating, better to red fire ant phagostimulating effect, can propagate fast and effectively in ant group.
3, red fire ant is large to bait formulation food ingestion of the present invention, and killing effect is remarkable.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
Embodiment 1
The present embodiment bait formulation is prepared from by the raw material of following weight: ethiprole 0.05 gram, Nipagin complex esters 0.5 gram, cassava ground-slag 70 grams, 20 grams, molasses and 9.45 grams, water.
Preparation method is: get raw material according to above-mentioned weight fraction another name, by ethiprole and molasses, water mix and blend 1 hour, then adds cassava ground-slag, Nipagin complex esters, mixes, namely obtain killing red ants bait formulation.
Embodiment 2
The present embodiment bait formulation is prepared from by the raw material of following weight: ethiprole 0.2 gram, Nipagin complex esters 0.35 gram, cassava ground-slag 78 grams, 15 grams, molasses and 6.45 grams, water.
Preparation method is: get raw material according to above-mentioned weight fraction another name, by ethiprole and molasses, water mix and blend 1 hour, then adds cassava ground-slag, Nipagin complex esters, mixes, namely obtain killing red ants bait formulation.
Embodiment 3
The present embodiment bait formulation is prepared from by the raw material of following weight: ethiprole 0.1 gram, Nipagin complex esters 0.2 gram, cassava ground-slag 85 grams, 10 grams, molasses and 4.7 grams, water.
Preparation method is: get raw material according to above-mentioned weight fraction another name, by ethiprole and molasses, water mix and blend 1 hour, then adds cassava ground-slag, Nipagin complex esters, mixes, namely obtain killing red ants bait formulation.
trapping test
By the killing red ants bait formulation in embodiment 1, embodiment 2 and embodiment 3 and certain brand killing red ants bait formulation (containing fipronil) and do not carry out trapping comparative trial to red fire ant in the wild containing the blank bait formulation of insecticide, certain brand killing red ants bait formulation (containing fipronil) is organized called after control group, by blank for blank bait group called after group, and the quantity of active mound when observing 5 days, 10 days, 15 days, 20 days, 25 days and 30 days, the results are shown in Table 1.
Table 1 killing red ants Contrast on effect
Above-mentioned experimental result shows: killing red ants bait formulation of the present invention compared with control group and blank group, movable red fire ant anthill decline rate is obviously higher, and killing effect is remarkable, and this killing red ants bait formulation is with low cost, has a good application prospect.
